7 Claims. (01. 220-97) This" invention relates to' a metal box: of thetype designed for piling one box: on the other; and has for one ofits-objects to. provides. box which while providing a shelf extendinginwardly'from' the wall thereof willibe sufficiently strong;

to sustain the weight of loaded boxes above it.

Another object of the invention is to provide a box which will bestronger and better: resist crushing strains than were the side walls ofthe boxin a single plane.

Another object of the invention is to provide abox the walls of which:may be thin with the strength of the box obtained from the strip ofstock around-its upper edge: and the positioning of thispart in place.

Another object of the inventionis to provide a box which will bestrongyand will effectively resist crushing or distortion frompressureswhich may be applied in the direction of its diagonally oppositecorners.

Another object of-v the invention is to provide a box the upper edge-ofthe walls of which need not Fig. 3 is a fragmental. perspective view ofa portion of the strip to be positioned along the upper edge of the boxand showing one. corner;

Piling boxes with which I am familiar are usually made by deflecting theupper edge portion of the verticalwallofthebox to provide a shelf forthe resting of the next box to. be piled upon it. When thev wall of abox is deflected in this manner weights from above when the attain acertain amount will collapse the walls of the box because of theincrement of the loadwhich is: out. of line withthe plane of; thewa'll.Ihave found, however, that by causing the wall to. be upright and in asingle plane and then by provideing-a shelf of a separate piece ofstock'acrossthe edge of the wall, I do not'ne'ed'to' finish. the edge ofthe wall and the wall. will sustain a much greater weight. Further, byproviding a strip of shelf. material around the edge of the. box in thismanner I may make the box of much thinner stock and the support attainedby a continuous strip' about the box or a stripwhich is welded at thecorners. makes astronger box :andyet a box which. has no greater weightthan heretofore; and the following is armore. detailed description of.the present embodiment of. this invention, illustrating the referredmeans by' which. these advantageous results may be accomplished:

With reference to the. drawings, l0 designates generall'y'a pilingbox'which is so constructed that a box: similar to it may be set: intothe. rim. and upon the-shelf portionat the upper edge of the box. Thisbox is formed of sheet metal and comprises a bottom ll, end'walls l2 andI3 and side walls I4" and I5. These walls are suitably securedibyportions of one overlappingthe other as at l6 and I1 and being spotwelded as at. 18. The upper edge of the wall such as l 9, seeFig- 2,neednot be finished and is toppedor capped by the shelf portion 20 of astrip of material which extends along the top edge of each of the walls.

Thisshelf portion 20 is provided with a rim 2| extending. upwardlytherefrom: at substantially right angles to the shelf and isconveniently rolled outwardly as at 22v to provide a smooth edge 23. Insome instances-however, the wall 21 may terminate in a finished edge 24'as shown in Fig. '7, while" in other instances the. wall 2| maybe rollednot only outwardly as at 22, see Fig. 8',v but also again inwardly as at25- so as to provide a triplethickness of mm for greater strength.Alflange 26 extends" downwardly from the inner edge: of the shelf 20 atan angle of approximately 45 although the particular angle maybe varied,and thence downwardly as at 21 in face toface contact as at 28 with. thewall. It. and this flange is spot welded. as" at 29 to the wall l4 atvarious points along its length.

In positioning the strip of strengthening material upon the edge of thevertical walls of the box the stripshapedas shown in Fig. 4 is notchedas at 30 through an angle of in the shelf and: flange portions" whilethe rim portion 2| remains uncut. The rim is then bent as at 31,.seeFig-B, so as to bring the edges 321 of thenotch 30 into contact as at33 where they are welded as: at 34, see Fig. 5. These notchesaresuitably placed and thebends occur at'suchpositions that. the strip ofmaterial will extend about the rest upon the upper edge of the verticalwalls as 'by a rim 39.

point where it extends along the opening 4| of wall in face to facecontact therewith and here secured together at intervals along saidface-toface contact portions.

' 3..In a metal piling boxv 'having'upright walls each in a singleplane, a shelf extending about 7 -said walls at substantially rightangles thereto provide a very firm and rigid support at and about theupper edge of the box.

By reason of the fact that the walls such as l2, l3, M or l5 are in asinglevertical plane and a triangular structure is formed between theshelf and the wall by reason of the flange which is attached to thewall, the wall supports the strip;

and the strip supports the wall and much greater weights than heretoforepermissible may 'be stacked upon the box and will be well sustained.

In some cases it is desirable to provide a hopper front for a box asillustrated in the showing as at 36 in Fig. 9. Here, one end wall istilted outwardly as at 31 with its end portions 38 joining the cornersof the verticalwalls and is supported In this instance the strip 40 atthe the hopper front is rolled outwardly rather than as heretoforedescribed, and along the wall to provide anarcuate portion 42, as shownin Figs.-

and 11, and this may occur wherever an opening is provided in'the boxwhether it be for a hopper front or for a handle opening, as will bereadily apparent. However, a handle such as 43 may be suitably. attachedto a bracket 44 secured to the end walls of the box.

The rim 2| is of such a dimension'across the box, as it extends up fromthe shelf, that the bottom of the box'will readily'be guided into aposition on the shelf .22 and there maintained against sliding eitherlongitudinally'or transversely of the box. a

The foregoing description is directed solely towards the constructionillustrated-but I desire it to be understood that I reserve theprivilege of resorting to all the mechanical changes to which the deviceis susceptible, the invention being defined and limited only by theterms of the appended claims.

I claim:

2. In a metal piling box having upright walls, each in a single plane, aone-piececontinuous shelf extending about said walls at substantiallyright angles thereto and resting directly upon the upper edges of thestock of the walls and with the ends of the shelf in abuttingrelationship, said shelf extending a substantial distance inwardlyand'outwardly'of the said walls, a rim extending downwardly from theinner edge of said shelf and at an angle thereto into contactwith saiduprightwall, and thence downwardly along said and resting directly uponthe upper edges of the stock of said walls and extending a substantialdistance inwardly and outwardly thereof, a rim extending upwardlyfromthe outer edge of said shelf, a flange extending downwardly from theinner edge of said shelf and at an angle thereto into contact with? saidupright wall, and thence downwardly along said wall in face to facecontact therewith, and means for securing said flange and wall in saidface to face contact 'at' intervals along its length. i

In a metal piling box of generally rectangular shape, four uprightwalls each in a'single plane, a single integral reinforcing strip ofmaterial extending along the upper edge of said box walls comprising ashelf positioned at substantially right angles to said walls and restingdirectly upon the upper edges thereof and extend ing substantially equaldistance on each 'side of said walls, a rim extending upwardly from theouter edge of said shelf, a flange extendingdo'wnwardly from the inneredge of said shelf and towards said upright wall and into contactthere-' with, and means tosecure said flange to said wall,
